Verified Spec-Driven Development

Verified Spec-Driven Development (VSDD)

The Fusion: VDD × TDD × SDD for AI-Native Engineering

Overview

Verified Spec-Driven Development (VSDD) is a unified software engineering methodology that fuses three proven paradigms into a single AI-orchestrated pipeline:

  • Spec-Driven Development (SDD): Define the contract before writing a single line of implementation. Specs are the source of truth.
  • Test-Driven Development (TDD): Tests are written before code. Red → Green → Refactor. No code exists without a failing test that demanded it.

Netflix's web architecture reverse-engineered from live network traffic -- 18 named internal systems (Akira, Cadmium, Shakti, Pinot, MSL, FTL, Ichnaea...), dual API migration (Falcor → GraphQL), video streaming pipeline, DRM flow, search capability negotiation, and the full content data model. All from 177 captured requests.
